It's a bit irritating but I'm glad I started down this journey because it looks more and more like I'm going to be avoiding the internet
If enough people complain, those services will start caring. If all they see is "one user complains every 3 years", they will just ignore it. That's how it works.
If you don't have a static IP you need will want to think about a MX relay service too ~ although mail is surprisingly tolerant of offline MX hosts if you can wait a little bit for your mail.
I feel this more and more each day.
My current de-google project is categorizing all my pictures on my local NAS to create the memories feature (where it shows historic pics on multiple theme axes). You can get really far with just a few hours of work a month to de-google and some off the shelf image embeddings.
The hero project in this category — what one cannot do trivially as an indie dev — is creating a great fresh PoI dataset. This is tough to do on a planetary scale because its a societal cooperation problem.
Banks are implementing terrible "security" checks. Users of alternative OSes should be a lot more vocal: change bank, but also complain a lot to the offending one, and make sure to leave them a bad review on the Play Store.
Actually people not using an alternative OS but caring about that should also leave bad reviews to those banks on the Play Store.
At the end of the day, the problem comes from humans in those banks who don't understand and don't give a shit. The only way to make them care about it is to complain enough that it becomes their problem.
I'm on a similar journey and I use Radicale.
If you need to share files externally, Nextcloud works very much like Google Drive and allows the creation of sharable links.
